DESCRIPTION:
Russ McRee has discovered a vulnerability in SilverStripe, which can
be exploited by malicious people to conduct cross-site request
forgery attacks.

The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. delete an administrative user
or delete an image by tricking a logged in administrative user into
visiting a malicious web site.

The vulnerability is confirmed in version 2.4.2. Other versions may
also be affected.

SOLUTION:
The vulnerability is fixed in version 2.4.3-rc1 and 2.3.9-rc1.
